Airport connection lost after sleep mode

Hello everbody,
Each time I send my PowerMac G4 MDD Dual 867 to sleep it won't to connect to my (or rather to any) Airport network anymore after waking up, it just seems as if Airport is completely defunct after waking up.
My iBook G4 works without any problems on the same network, by the way.
I know the workaround with restarting IPv4 networking (described here: http://discussions.apple.com/thread.jspa?messageID=1122310&#1122310) and I have also created an AppleScript for automatising this process, however I am still wondering, if this issue will ever be addressed by Apple, since it is still present for me in 10.4.6.
Best regards,
Björn Wilmsmann

Okay, this might not solve your problem, but I had a similar problem when I switched from WPA2 to WEP on my Airport, therefore also changing the password which again somehow got my Powerbook confused.
I went into System Preferences > Network > Airport and looked at my "Preferred Networks" list (Not "By default, join..." > "Automatic"). Then I edited my airport network in that list (the small "Edit" button) and I saw that the password somehow was corrupted. When I corrected this error my Powerbook began joining automatically after sleeping again. Strangely, this setting has nothing to do with the Keychain Access, even though you can find your base station's password there too...
Oh, and I might add: My airport is on a closed network and is therefore not "visible"...

  • Connection lost after sleep mode

    When my computer comes out of sleep mode, it's not connecting to the Airport wireless connection.  Waiting doesn't seeme to matter...the icon on my iMac (upper right on screen) shows no connection.  I have to manually turn off Airport and turn it back on to get it to connect (turning it off and on using the icon).
    I have made zero changes to my system, other than that we moved to a new home.  No equipment changes...no settings changes.  What the heck is going on to cause it to no longer connect when coming out of sleep mode?  And more importantly, how do I fix that?  Thanks very much!

    Try the following, in order, until (hopefully) resolved:
    1a. Delete Preferred Network(s)
    System Preferences > Network > AirPort > Advanced > AirPort tab
    Under "Preferred Networks," delete the network(s) you regularly use from the list.
    1b. Delete AirPort Keychain Entries
    Launch the "Keychain Access" application located in Applications/Utilties.
    Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
    1c. Add Preferred Network(s)
    System Preferences > Network > AirPort > Advanced > AirPort tab
    Add the preferred network(s) using the "+" button.
    Restart or log out then back in.
    2. Move System Configuration Files
    (Note: You will have to reestablish your network connections settings.)
    Go to /Library/Preferences
    Move the SystemConfiguration folder to the desktop.
    Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.)

  • Bluetooth connection lost after sleep mode

    I'm using a bluetooth keyboard with my iPhone. It works great. However, if the phone goes into sleep mode, it does not keep the connection and I have to re-establish the connection through settings each time. Is there a way to keep the connection or have it automaticaly reconnect?

    I use the Apple bluetooth. When I sleep my iPad it actually puts the keyboard to sleep. Probably to save the batteries. When I wake the iPad, I still have to go to the Bluetooth and reconnect via the iPad. The keyboard automatically turns back on so I don't have to power it on. I think that is the best you could hope for.

  • Why is wifi connection lost after sleep/wake mode?

    I've had this iMac a little over a year and had not experienced this until a few days ago.  Every time my computer comes out of sleep mode the wifi is no longer connected.  I must turn it off wifi and turn it back on again to re-establish a connection.  Any suggestions? Thx!

    Hello tim290,
    After reviewing your post, it sounds like after the computer wakes from sleep it does not connect to the internet. I would recommend that you read this article, it may be able to help the issue.
    Wi-Fi: How to troubleshoot Wi-Fi connectivity - Apple Support
    Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
    After waking from sleep or starting up, your computer may not show that it is connected to a Wi-Fi network.
    After start or wake, your computer may indicate that it is connected to a network, but does not connect to the Internet.
    Solution
    Use these steps if your computer does not automatically connect to your desired Wi-Fi network.
    Check your TCP/IP settings in the Network pane of the System Preferences. Click the "Renew DHCP lease" button
    Choose System Preferences from the Apple menu.
    Choose Network from the View menu.
    Select Wi-Fi, then click the Advanced button in the lower-left hand corner of the screen.
    Click the TCP/IP tab from the top of the screen.
    Click the "Renew DHCP lease" button.
    Select the Wi-Fi tab and view your Preferred Networks list.
    Select each network and click the minus (-) sign to remove those networks from your Preferred Networks list.
    Click OK and close the Network preferences.
    Remove your stored network passwords using the Keychain Access Utility.
    Open Keychain Access from /Applications/Utilities. Your window will look like this:
    Remove your AirPort network passwords from the login keychain: Select the "login" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
    Remove your AirPort network passwords from the System keychain: Select the "System" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".Note: The above steps will remove your Wi-Fi network passwords. If you do not know them, or if your network does not use passwords to restrict access, you should contact your network administrator.
    Restart your computer.
    Join your Wi-Fi network. You will need to enter your password for your network again if it requires one.
    Thanks for using Apple Support Communities.
    Have a nice day,
    Mario

  • Server connections are lost after sleep mode with Mavericks.

    Ever since I "upgraded" to Mavericks, when I "wake" my iMac after putting it in Sleep mode, the network connections have disconnected and I have to re-connect all of them (6) every day. This never happened with Mountain Lion or any other previous version of OS X. Is there a fix for this?

    I've also noticed this problem. Brand new MBP with Mavericks, goes to sleep, on wakeup all my network drives are disconnected, as is Outlook 2011. None of them recover gracefully - I have to manually reconnect. Aggravating..

  • Wifi connection lost after sleep

    Hello guys,
    I have a MacBookPro retina 15" and every time my mbp go in sleep mode it lost the wifi connection...
    Someone solved this issue?
    bye bye,
    Oscar

    Test after taking each of the following steps. Back up all data before making any changes.
    1. Make sure the network is on the preferred list by following these instructions.
    2. Follow the instructions in this support article under the heading "Symptom: The network connection drops unexpectedly."
    3. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
    4. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
    5. In some cases, the problem has been resolved by repairing permissions on the startup volume.
    6. Reinstall OS X.

  • Wi-Fi Connection lost in sleep mode

    After upgrading to 3.0, my Wi-Fi connection is lost as soon the iPhone gets into sleeping mode. After unlocking the connection doesn't wake up. New Bug?

    there's now an option to Auto-Join each specific network. It might default to no for your wifi network. Just clock on the blue arrow next to the network name and tell it to Auto-Join.

  • Wireless Connection Lost in Sleep Mode

    I connect to the Internet via an Airport Extreme Base Station and a Toshiba cable modem. It worked fine since I bought it in February, but in the past couple of days, my Powerbook loses the connection with the Airport whenever it goes into Sleep Mode and I have to go back into System Preferences and reselect the Base Station to regain it.
    I've tried resetting the Airport preferences and turning off the computer to reboot. I've also reset the Base Station itself.
    Any suggestions?
    PowerBook G4   Mac OS X (10.4.3)  

    Let's see. So you bought 250mb data and ran thru it, then purchased unlimited.
    People seem to not understand a few things. First, 250mb of data is nothing. If you are not a "techie type" perhaps you should have researched exactly what you can do with 250mb. Ten images from my Nikon are OVER 250mb. Second, you paid 15 bucks for 250mb data and as I said, ran thru it. You got your 15$ worth of data. What do you want refunded??
    Third, then instead of waiting until your month was up and you got another allotment of 250mb you didn't want to wait and chose to go on the unlimited plan. That plan started that day and will last for 30 days. What exactly do you feel should be refunded? The 250 you used, or the unlimited which you plan to use?
    So to recap:
    1. You have no idea how much data you can stream for 250mb.
    2. You paid for 250mb data and used 250mb data.
    3. You then paid for unlimited data, which is your current situation.
    4. You then called Apple (which has nothing to do with AT&T billing) and are now mad because no other cell phone provider has the micro sim AND come here to trash the "techie type" who honestly answered your question.

  • Wireless Connection lost after sleep: iMac 27-inch

    When my iMac goes into sleep mode, or logs off after pre-determined time, it loses the wireless connection to the router. I then have to go to the upper right of the screen, select my router from the list of available routers, and force a connection.
    Has anybody else experienced the inability to maintain persistent wireless connections?
    Thanks!

    I had the same problem for weeks with my new 27" iMac.  I tried resetting p-ram, adjusting network settings, throwing out preferences for network settings - - - everything!  Nothing worked.  I final called Apple support and they told me to unplug EVERYTHING from the Mac, including power, wait 30 seconds, and reboot.
    Works fine now.
    Hope that helps!

  • Internet connection lost in sleep mode

    My internet connection dies when going into sleep mode. What can i do to fix this?

    +My internet connection dies when going into sleep mode. What can i do to fix this?+
    It's not broken. Don't put your computer to sleep manually and do change your Sleep settings on the Energy Saver pane of System Preferences. Your entire system can operate without interuption when "Put the display to sleep" is activated, so that time can be shortened while you lengthen the amount of time the computer will be awake to something more convenient - or set it to "never."

  • Wireless Internet connectivity lost after sleep

    I've got a problem where I keep losing my wireless network connection after going to sleep.
    The situation is that I'm connecting to my university's secure network. I have the credentials saved on my MacBook. When I need to go and leave my computer on my desk, I go back to the login window, and close the lid. When I come back and open it again, I'm instantly asked for the network password, at the login screen. Regardless of whether I enter it or dismiss the dialog, I'm unable to get a connection automatically after I resume my user session. There's an exclamation mark on the network icon and it says that there's no internet connection on the menu. When I click on this warning, I'm asked to repair the network connection and re-connect to it. This works, but I'd much rather that this be done automatically. Is there no way for me to resume connectivity after waking up my MacBook without having to manually re-connect?
    Thanks in advance for any suggestions.

    The problem's still happening in 10.6.2. I lose my Internet connection when I go back to the login window, then close the lid on my MacBook so that it goes to sleep. When I awake it, and log back in, I'm shown as being connected to the network, but not to the Internet. I have to manually re-connect.
    When I just close the lid without exiting to the login window, it appears that my Internet connection is re-established automatically, though, on re-awakening. I'm puzzled as to why this is occurring. It looks like a bug to me.

  • Airport connections lost after upgrade to Snow Leopard

    After upgrading to Snow Leopard, I am no longer able to connect to the Internet wirelessly.  I have had to resort to connect via wired connection.  I have tried to reconfigure the connection.  It finds my wireless network, but when I type in my password it says it is not correct.  I know it is an issue with Snow Leopard as it worked fine prior to the upgrade and my other devices connect with no problem.

    Go into Displays Preferences and, if you haven't already done so previously, put a checkmark in the box for "Show displays in menu bar". Then, click on the resulting icon that shows up in the menu bar to drop the menu and select "Number of Recent Items" and set it to 10. Now drop the menu a second time and see if there are two 1920 x 1080 resolutions. If so, one of them may be the older one previously in use that was working.

  • Airport connection "lost" after upgrades

    My husband updated his computer (iBook G4, running Mac OS 10.3.9) this morning, and has been unable to access any airports since. When I checked into the System Preferences, it showed nothing under the TCP/IP, even with the choice of select "Using DHCP." Clicking on the "Renew DHCP License" did nothing, either. The airport shows in the list on the menu bar, and it has a check in front of it, it's just that the network cannot be found.
    I also tried to run the airport admin. utility, which could not find the connection, either. Any help is greatly - and desperately - needed!!!
    Thanks,

    iBook G4 Mac OS X (10.3.9)

    I had the same thing happen to me yesterday, I have an ibook running 10.39. I have my dsl plugged directly in now but I haven't figured out how to get airport to work again.
    If I figure it out, I will post, in the meantime I hope someone with a wonderful solution posts...

  • Mail Connections Lost After Sleep - sum up the sollutions?

    In https://discussions.apple.com/thread/4268728?tstart=0 9 pages are spend on possible sollutions to this problem.
    I had this problem, then it disappeared for quite some time, but now I have it again. I not remember what I did at the time, possible a suggestion from these 9 pages.
    - Is there an overview that someone has of all th possible sollutions, I am a bit hesitant in going through all the options.
    - it seems, looking at the last page, that there is not one sollution? which ones work best?
    Thanks

    Try a restart.
    Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.
    Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
    Isolating an issue by using another user account
    If the problem is still there, try booting into the Safe Mode.  Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application uninstaller. For each disable/delete, you will need to restart if you don't do them all at once.
